  • Thoughts on DIY LED (the never ending story)

    Oh! Another neat trick for you to know.

    Talking about heat dissipation and heat sinks. If you want to avoid using noisy fans and wasting electricity on them (though a 100mm 12VDC muffin fan doesn't suck all that much juice and nor does it make a terrible noise) pick a heat sink with vertical fins instead.

    Yes indeed. Your fat solid sink with a thick plate and up blades (the like of Bart Simpson hairdo) needs air circulation via a fan forced air-flow. It works without fans, but not to total perfection. You still follow me?

    The "star like" round heat-sinks will induce a natural convection all on their own. But it is for you to test and decide. I am just telling you the basic principle. Yes, I know. Those are a pain in the a** to implement in a sound and strudy design. I guess we have a laugh here...

    But in any event, at least, by using one star shaped heat-sink per LED, you are protected against short-circuits that could happen on a single slab for all.

    So long...
